Contact with monkeys and apes puts populations at risk

Animal diseases that infect humans are a major threat to human health, and diseases often spillover to humans from nonhuman primates. Now, researchers reporting in PLOS Neglected Tropical Diseases have carried out an extensive social sciences evaluation of how populations in Cameroon interact with nonhuman primates, pointing toward behaviors that could put people at risk of infection with new diseases.

Zoonotic diseases— those which originate in other before spilling over to humans—now constitute more than 60 percent of emerging infectious diseases. Of these , 70 percent reportedly come from wild animals. Because of the similarity between humans and , these monkeys and apes serve as frequent reservoirs or amplifiers for pathogens that pose a risk to human populations.

In the new work, Tamara Giles-Vernick of the Institut Pasteur, France, and Victor Narat of the French Center for National Scientific Research, with their colleagues carried out surveys, real-time data collection, oral history interviews, and wild meat surveys to paint a full picture of the physical exposure of people in southeastern Cameroon to nonhuman primate species. Data were collected in 2016 and 2017 and included information from multiple villages and hundreds of people.

The researchers found that Cameroonian adults have frequent physical contact with primates, and more with monkeys than apes. This contact is most often through hunting, butchering, preparing and consuming meat, but also includes injuries sustained from gorillas. Some 85% of questionnaire respondents had eaten primate meat in their lifetimes. In general, the exposure risk in any given village was directly related to the relative density of nonhuman primates and their proximity to human settlements.

"National and international authorities should support improved surveillance of humans and abundant monkey species, as well as popular messages to promote safe meat handling practices," the researchers say. "Multidisciplinary social science and ecological approaches should be used to improve surveillance and communications with forest populations about neglected tropical diseases."

Another reason to screen immigrants before we let them into the country.

Build the wall.

We need that wall between us and Mexico to keep those Africans out.

So worm

You think all these diseases come from africa?

"During the Obama administration, the U.S. experienced a mass migration event similar to the German refugee crisis: the arrival of significant numbers of unaccompanied alien children.

"Their arrival was accompanied by significant increases in tuberculosis, dengue fever and swine flu infections.[11] Unaccompanied alien children also appear to have been the source of the deadly outbreak of the EV-D68 enterovirus that spread throughout the American West in 2014."

-Only a small taste. And let's not forget

"The U.S. Supreme Court ruled in Plyler vs. Doe (457 U.S. 202 (1982)) that undocumented children and young adults have the same right to attend public primary and secondary schools as do U.S. citizens and permanent residents. Like other children, undocumented students are obliged under state law to attend school until they reach a mandated age."

-dengue. Good for the immune system.

One more little tidbit

"Those diseases, like Yellow Fever, falciparum malaria , Kyasanur Forest disease, Tanapox and Mayaro virus depend on mosquitoes, ticks and biting flies to transmit from monkeys to humans."

We need to not have too many moslems, or as we called them when I was young....back when velociraptors roamed the earth and Alley Oop rode Dinny.....mohammedans. Still know how to spell that word as it was a favorite for teachers to sting us with on pop quizzes.

That said, One really CAN see a family resemblance between male orangs and that orange comboverd fool in the white house. Kinda an insult to the Orang-utan though cuz' they are pretty sharp critters. Remember Clyde who co-starred with Clint Eastwood and Sondra Locke in "Any
Which Way But Loose" ? Cute movie. Better than any they make now-a-days. Like that snake man....YUKKH!

Chinese humans 2.1 million years ago

Our ancient ancestors lived in China, too.
Ancient humans appear to have reached north-western China about 2.1 million years ago, and they lived there for hundreds of thousands of years
this child playing with his greater spot-nosed monkey
this Childs ancestors were playing with their greater spot-nosed monkey over 2.1 million years ago
whatever diseases this child is exposed to
his ancestor have been exposed to for 2million , 3million , 4million or more years
we are no more at risk to day
than when this child left his village 2.1 million years ago
and headed out to China
